Introduction
2026 is shaping up to be a game-changer for businesses in Belgium. The government’s move toward mandatory e-invoicing through the Peppol network isn’t just another compliance update—it’s the start of a new digital efficiency era. Picture this: no more manual invoice processing, no more lost PDFs, and no more email attachments getting buried in someone’s inbox. With the Peppol invoice format, Belgian companies are stepping into a world of precision, automation, and trust. But what exactly is Peppol, and how does this affect you? Let’s unpack it all—from what it means to how you can be ready in time.
Peppol service provider in Belgium
Before diving into formats and workflows, let’s talk about the real enablers of this digital revolution—Peppol service providers. These are certified access points that connect your ERP or accounting software to the Peppol network. Think of them as your digital post office for invoices—ensuring every document reaches the right destination, securely and in the right format.
In Belgium, businesses are rapidly aligning with certified Peppol access points to meet upcoming mandates. AAssureComply, for example, stands out as a trusted Peppol service provider in Belgium, empowering enterprises to exchange invoices with full compliance and zero friction. Their technology acts as your automation ally—taking care of validation, delivery, and audit trails behind the scenes. The result? Instant connectivity, faster payments, and peace of mind knowing you’re aligned with both Belgian and EU regulations.
Peppol invoice format in Belgium
Now, let’s get into the core of it—the Peppol invoice format. Unlike traditional PDFs or XMLs sent over email, the Peppol format follows a universal data structure: Peppol BIS Billing 3.0, based on the UBL (Universal Business Language) standard. This ensures your invoices can be read and processed automatically by any Peppol-enabled system, anywhere in Europe.
For Belgium, the 2026 model means all B2B and B2G transactions must use this standardized Peppol format. Each invoice will include mandatory fields such as VAT details, order references, structured payment data, and tax breakdowns.
Why is this such a big deal? Because it creates data interoperability. Whether you’re billing a small retailer in Antwerp or a government office in Brussels, your invoice lands in their system, validated and ready for payment—no translation, no rework.

So, how does Peppol e-invoicing in Belgium actually work? In essence, Peppol isn’t just a platform—it’s a secure, interconnected network used across Europe (and increasingly, worldwide) to exchange e-documents like invoices, credit notes, and purchase orders. Belgium has already made Peppol mandatory for B2G transactions, and the B2B extension rolling out by 2026 means complete digital integration across supply chains.
Here’s how the Peppol flow looks:
1. You create an invoice in your ERP or accounting system.
2. Your Peppol access point (like AAssureComply) validates and sends it through the Peppol network.
3. The recipient’s access point receives and integrates it directly into their system.
No emails. No downloads. No delays.
